To all whom it may concern:

Be it known that I, HENRY T. DUNLAP, of Galesburg, in the county of Knoxand State of Illinois, have invented certain Improvements in Book-Clips,of which the following is a'specication:

YThis invention relates to improvements in book-clips; and it consistsin a double-jawed clamp provided with a closing-spring, and soconstructed that one pair oi' the jaws may be made to hold the leaves ofone 'side of the book, and the other pair ot' jaws the leaves of theother side, the pairs of jaws connected with each other in such a mannerthat they may be operated simultaneously, all as hereinafter fullydescribed.

ln the accompanying drawings, forming part of this specification, Figurel is a perspective view of my invention in place on a book; and Figs. 2and 3 are, respectively, side and end elevations thereof.

Referring to the parts by letters, letters A represent two barssimilarly formed, their central parts a curved, as shown in thedrawings, and their ends ci straight.

Reference to Fig. 1 will explain the operation of the invention almostwithout further explanation. By taking hold of the bars A at a they maybe pressed together at that part and separated at the jaws a. The jawsmay then be placed on the book, as shown at said Fig. 1, and, thepressure being removed from the parts a, the spring b will draw the jawsof each pair of springs toward each other and clasp the leaves of eachside of the book snfticiently close to retain them in the desiredposition.
